Be it known that 1, ADOLPH SCHNEIDER, a citizen of the United States, residing at'Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling-Valves, of which the following is a specificatiom The object of this invention is to construct a valve especially adapted for use in the bottling of liquids under pressure and in which the bottling operation is performed under the conditions of equal pressure in the receptacle' from which the liquid is drawn and in the bottle, for the equal pressureto act and prevent the foaming of the liquidin the bottling operation,and alsoinsuringagainst deterioration of the liquid or loss in, the bottling opuid under pressu re which will enable the pressure to be admitted to the bottle before the admission of the liquid; to improve theconstruction of the valve as regards the retention of the valve-plug within the valve casing or shell; to separate the Iiq'uid pasSage and the pressure-passage,-s o as to give the liquid and the pressure separate lines of travel in entering into and passing'outthrough the valve; to improve the construction,"arrange;

ment, and location of the filling-tube in its relation to the filling-plug and the passages in the plug for the liquid and pressure,.aud to simplify and improve the construction and operation of the constituent elements which enter into the constructionof. the valve and the filling-tube cooperating with the valve.

The inventionconsists in the features of constructionand combinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is an end elevation showing the preferred form of construction for the valve as a whole; Fig. 2, a side elevation of theconstructio'n shown in Fig. 1; Fig. 3, an end elevation showing a modification in the formation of the casing or shell carrying the valve-plug; Fig. 4, aside elevation showing a construction onthe general plan of the construction of Figs. 1 and 2, but having a fixed plug instead of a fixed casing or shell; Fig. 5, a longitudinal, section of the construction shown in'Figs. l and 2; Fig. 6, a cross-section on line 6 of Fig. 5 looking in the direction of the arrow, with the fillingtube removed; Fig. 7, a cross-section on line 7 of Fig. 5 looking in the direction of themrow, with the entered end of the filling-tube into'the plug-valve in sectionand with the filling-tube (notshown) below the closing-cap; Fig, 8, a plan sectional view of the casing'or shell for the plug-valve, showing the ports or openings in the casing-or shell in full lines and the passages in the plug-valve in dotted lines in the position they occupy with the initial establishment of communication for the pressure to enter the bottle and the liquid port and passage-closed against admission of liquid; and Fig. 9, a cross-section similar to Fig. .6 of the construction shown in The construction vof valve -of Figs. 1 and 2 has a casing or shell A, with a tapered interior chamber or opening for the reception of;

a plug-valve. The chamber of th elcasing or shell at one end is closedbya c'apor headB and at the other end is closed bya capor the terminus of its screw-threaded body. has

,a flange b, which when the plug is fully entered abuts tightly against the end face of the rim a, making a close tight joint. The

opposite end of the shell or'casing has a rim. '0, with an interior screw-thread, into which is screw-threaded the closing caper head B, and the cap or head, adjacent to its screwthreaded body, has a fiange'b,'whic"h when the cap or head is fully entered abuts against the end face of therim a, making a close tight joint, and, as shown, each cap or head ICO has in its outer face a slot or recess b for the reception of a screw-driver or other suitable instrument by means of which the caps or heads may be entered fully into place.

The casing or shell A has located in its chamber a controlling-valve D for theliquid and pressure, which valve, as shown, is in the form of a tapered plug fitting the correspoudingly-taperetl chamber of the casing or shell. The length of the plug-valve is less than the full length of the chamber therefor in the casing or shell, leaving a space in the arrangement shown between the face of the wide end of the valve and the closing cap or head B, in which is located a pressure-spring C, which spring exerts a sufficient force to hold the valve pressed inwardly with the requisite frictional contactbetween the walls of the plug-valve and the chamber of the easing or shell for holding the valve and the filling-tube against the filling-tube falling back when the valve is turned to shut 01f the passage therethrough of the liquid and pressure, and the spring also serves the purpose of holding the plug in its chamber, so as to maintain a close tit for the valve in its chamher, making a tight joint' against leakage. The plug-valve has transverselytherethrough a hole or passage,which,as shown, is circular in cross-section and of dilierent diameters between its ends. The smallest end of the hole or passage transversely through the valve forms a port or opening d, and the section cl of the hole or passage adjacent to the port or opening d is screwthreaded to receive the end of the filling-tube, and the opposite end (1 of the hole or passage to the port or opening d is of the greatest diameter and has a screw-thread for the attaching of the closing-cap on the filling-tube. The fillingtube E at its inner end is screw-threaded and entered into the hole or passage of the plugvalve, the screw-threads on the fillingtube end engaging the screw-threads of the section (1 of the hole or passage, and when in place the hole of the filling-tube will be in alinement with the port or passage cl in the plug-valve, as shown in Figs. 5 and 7. The filling-tube is of a length so that when inserted in a bottle it will extend down therein a sufficient distance for the filling operation, and, as shown, the extreme end of the fillingtube has on one or more sides a discharge port or opening 6, which when the end of the filling-tube is in the neck of the bottle allows the liquid to discharge into the bottle. The filling-tube, as shown, has in its interior a vent-pipe F, which at one end is in comm unication wit it a port or openingf through the wall of the filling-tube and at its other end is in communication with a port or opening f in the wall of the filling-tube, and this pipe also serves the purpose of a pressure-supply pipe for admitting a pressure corresponding to the pressure in the filling-tank into the bottle before supplying liquid to fill the bottle. The body of the filling-tube above the port or openingf is encircled by a closing-cap G,

which has a neck G with an exterior screwthread to enter the screw-threaded section 61 of the hole or passage through the plug-valve, and the neck G passes through an elongated slot or opening 9 in the casing or shell of the valve, which opening is of sufficient length to allow of the necessary turning of the plugvalve to shut off and admit liquid and pressure to pass through the valve. The closing cap, as shown, is of a semicircular shape and at its outer opeq end has an inwardly-extending ledge or flange g, against which rests the lower edge face of a packing orcnshion H,of rubber or other suitable material, and, as shown, the packing or cushion has a central conical depending closure or stopper h, which when the filling-tube is in the neck of the bottle enters the mouth of the bottle andin connection with the packing or cushion I-I tightly closes the mouth of the bottle against the escape of liquid and pressure when the neck of the bottle at its end is held against the packing or cushion H of the closing-cap.

The plug-valve has an annular or circular passage or chamber 0 encircling the body of the filling-tube and into which the port or openingf of the vent and pressure-supply tube opens. The casing or shell A on-its upper side in the construction shown in Figs. 1, 2, 4, 5, 6, and. 7 has a rim or wall I, through which and into the body of the casing or shell is a passage t', which terminates in a port 01, with which the discharge-passage of the plug can be brought into alinement for admitting the liquid to enter the filling-tube and be discharged therefrom. The wall or rim I, as shown, has an interior screw-thread for the reception of a coupling 7'0n the end of a supply pipe or hose J, leading to the source of liquid-supply. The plug-valve has therein a passage is, which is in communication at its inner end with the annular passage orchamher 0 around the bodyof the filling-tube, and the receiving end or mouth it of the passage 7.: is elongated transversely of the valve. The receiving end or mouth when the plugvalve is properly turned, is in communication with a discharge end or mouth of a passage ls in the top wall of the casing or shell, and this discharge end or mouth 70 is elongated transversely to correspond with the elongation of the receiving end or mouth of the passage in the plug-valve. The passage 70 in the arrangement shown has entered thereinto a short pipe or tube K, and connected with the tube or pipe K by, a suitable with the turning of'the plug-valve in the proper direction the passages 70 and 7c? and the, ports or openings (1 and t" are closed against the admission of pressure and against the passage of liquid; but with the turning of the plug-valve in the direction for filling the bottle the initial movement in turning the plugvalve will open thepassages 70 and k by rea-.

son of the elongated months 76' and k allowing pressu re to flow into the bottle before the admission of the-liquid, with the result-of placing the bottle under a pressurecorrespondin g to that of the pressure on the liquid. The further turning of the valve into position for the filling fully opeusboth the pas sages la audio -for the admission of pressure and the passages daand t" for the, admission of liquid, so .that the liquid will enter thebottle under the same pressure as the pressure onthe liquid, thus insuringthevbottling of the liquid under an equal pressure in the bottle,thereby preventing anyfoaming in filling the bottle and insuringthe bottling ofthe liquid without waste and deterioration.

The .liquid fiows' from the filling -,tank.

throughv the pipe or hose J, and with the ports or passagesfdfand if in;line the liquid will; flow through the filling-tube and be discharged therefrom atthe portor opening c into the: bottle, and with the fillingof the bottle as the liquid rises therein the pressure will be expelled, passing out through the vent-tube F into the circular orannular passage or chamber c and through the passages 7c and 74:

into the pipe or hose L-back to the source'of, supply, which maybe-the filling-tank. The, bottle when filled, together withthe fillingtube, is swung out of the filling position,,and themovement in so doing turns the plug.-.

valve to close the .fiuid passagesand ports and the vent. movement opens the vent and pressurepassages for equalizi-n g the pressure and the fullmovement to a filling position, for the fillingtube opens the liquid-passages-and the vent and pressure-passages, withthe result that the liquid entering by a gravity flow will forceout the pressure in the bottle, making the 'filling operation one under the condition of equal pressure in the tank and bottle.

The construction in,-Figs 3 and 9 insteadof having a small wall or rim for the attachment of the liquid-supply pipe or hose has a neck I With an exterior screw-thread for at taching the valve by a coupling to a filling tank, the neck and the wallet the shell or.

casing having therein the passage 2' and port t" and the passage 10 for the attachment. of

Itwill be seen that the initial construction so far as concerns the form of;

the plug and the-liquid-passages andtheyent and pressure-supplypassages in the same as described for the construction of valve =of Figs. 1, 2, 5, 6, and 7. j

. The benefits and advantages of a valve hav, in g theliquid-passages and thevent and pres-V, sure-supply passages can be obtained;by hav--; ing the plug-valve held in a fixed relation and; the casing or shell movable thereon, and a! construction of this'nature is shown-in Fig. 4. The casing or shell A is of the same'gen eral construction and-arrangement as thecasing or shell of Figs. 1 and 2 except, that the casing or shell A has thereon a handled/, by which the casing or shell can ;,be-turned.-to' bring thepassagesin coacting relation. .=.T he';

plug-valve Dv is entered into its chamber in;

the casing or shell and at one end has a square projection b and its other end ;has asquare projection with a threadedstem 19 extending. out therefrom. The square extensions of the;

plug-valve are-entered into correspondingly-1 shaped recesses or openings; therefor -ii1-=depending arms or bars M,each bar having;a; turned end m for fixedly attachin thearms in position to a support bybolts or otherwise.

The stem b is screw-threadedand ,has thereon a nutob which abuts against a washer-b by means of which nut the pl lgwvalveqis:

drawn intothe chamber, so as to-Inake a'tight fit and-provide a close joint against;leakage.-; f

The operation is essentially the'same as described for the construction of, Figs. 1 and-2 -IOO except that the casing or shellis, turnedxto bring the liquid-passages and the vent andpressure supply passages into communica-- tion and carry these passages outof commu-; nication with the same result so far,as sup-; plying an equal pressure between thefillings. 7 tankand. the bottle to be filled asth-e result, attained in the construction 0fFigs/1and 2. 'Ihe:filling-t11be,w.ith its closing-cap, is always in the same position by reasonof its fixed connectionto the'plug-valve, which is nonturnable, and the casing or shell is the'ele- IIO ment'by which the necessary communication I is established and-cutoff for theliquid-pasa sages andthevent and pressure-supply pas-1 sages.
